Seat belt tension sensor
First Claim
Patent Images
1. A seat belt tension sensor for attachment with a seat belt comprising:
- a) a housing;
b) an anchor plate at least partially mounted in the housing, the housing being movable relative to the anchor plate;
c) a lever mounted to the housing;
d) a magnet mounted to the lever; and
e) a sensor mounted to the housing, the sensor adapted to generate an electrical signal in response to relative movement between the magnet and the sensor, the electrical signal changing in proportion to the amount of tension on the seat belt.

Abstract
A seat belt tension sensor for measuring the amount of tension in a vehicle seat belt. The seat belt tension sensor has a housing and an anchor plate. A lever is mounted in the housing. The lever holds a magnet. A sensor is mounted to the housing. The sensor generates an electrical signal in response to relative movement between the magnet and the sensor. The electrical signal changes in proportion to the amount of tension on the seat belt. A spring is mounted in association with the housing and the anchor plate. The spring biases the housing from the anchor plate.
